Every field on the Billing details tab, what the taxpayer option changes, what the country field decides, and where to find your invoice and agreements.
You went to buy something and the panel said "Enter your billing details before purchasing." These details are not a formality: your invoice, the text of your agreements, the tax rate and which payment methods you see are all decided here. This guide covers every field and what it affects.

What we use the details for
Your billing details are a single record attached to your user account. There are no per-portfolio billing details; payments for every portfolio you own are invoiced with the same information.
That record is used in four places:
On the invoice — name, business name, address and tax details are printed on it.
In the agreements — the pre-information form and the distance sales agreement are filled in with your details.
In billing emails — order, payment, renewal and overdue notices go to the Billing email address here, not to your sign-in address.
At the payment provider — the payment page opens with this name, address and phone number.
Filling in your billing details
Open My user settings › Plan and invoices › Billing details.
If you are a registered taxpayer, tick the I'm a registered taxpayer box at the top. The form changes accordingly.
Fill in Full name. With the box ticked, the field is called Full name or business name.
Check the Billing email field. If it is empty it arrives pre-filled with your account email; change it here if your accounting team uses a different address.
Fill in Phone. You can include a country code; spaces, parentheses and hyphens are accepted.
Choose the Country. This choice also decides what the address fields below are called.
Fill in the address fields. In Türkiye you are asked for Province, District, Postal code and Street address, in that order, with the hint "Neighbourhood, street, building and apartment no" under the street address.
Fill in the tax fields if they appeared (see the next section).
Press Save. The screen reads "Billing details saved."
If you arrived from the checkout screen through the Edit link, saving takes you straight back to checkout; you do not have to rebuild the order.
The "I'm a registered taxpayer" option
The panel asks you one question, and that single box handles the distinction between companies, sole proprietors and private customers.
With the box unticked, only your name and address are asked for. In Türkiye a Turkish ID number field also appears, but it is not required; the hint under it reads "Optional. If left empty, the invoice uses the generic identity number."
With the box ticked, tax details become required:
In Türkiye two fields appear: Tax office and Tax number or T.C. identity number. A company enters its 10-digit tax number; a sole proprietor enters the 11-digit T.C. identity number. The number is validated against its check digit, so a wrong number is not saved.
Outside Türkiye a single field appears and its name follows the country: VAT number, EIN (employer identification number), Business number (BN) and so on. Below the field, an example in that country's format is shown.
Ticking the box is what gets the invoice issued with tax details. Sole proprietors are taxpayers too, so entering a personal name with the box ticked is perfectly valid.
What the country field decides
The country is not just part of an address; it directly decides three things.
The tax rate. The VAT (N%) row in the order summary is calculated from the country in your billing address.
The agreements you accept. Which documents are required and which are optional varies by country.
The payment methods. The checkout screen lists only the methods that work in your country. Change the country and the options change; if none remain, the screen says "No payment method is available right now."
The names of the address fields change with the country too: one country shows State and City, another Prefecture, a third ZIP code. The panel arranges which fields appear, in what order and under what name.
⚠️ Note: With no record yet, the country opens as Türkiye. If you are elsewhere, change it before your first save; changing it later does not correct the tax on your past orders.
Viewing your invoice and agreements
There is no invoice document to download in the panel. The record of your payments is the Orders tab, and each order's own page carries everything an invoice carries: the product, the service period, the list price, the discounts, the subtotal, the VAT rate and amount, the total, the payment method and the payment date. The Print button on the order page lets you print that summary or save it as a PDF.
The agreements you accepted with the order sit on the same page under Accepted agreements; View opens the exact text of that order, its version number and the date you accepted it.
Your full consent history lives on My user settings › My agreements. It lists every document's name, version, the context in which it was accepted and the date; documents accepted with an order carry a View order link. From that same page you can give or withdraw your consent to commercial electronic messages.
Changing the details later
You can update your details at any time; the new values apply from your next order onwards.
Every order stores a copy of your billing details as they were the moment it was created. So changing your address today does not change last month's order; that order stays on file with the old details. This is deliberate: a past document that later looks different causes accounting problems.
If you change the details while an order is awaiting payment, that order also keeps the old details. To be invoiced with the new details, cancel the pending order and create it again.
Common mistakes
Mistaking the billing email for the account email. Billing notices go to the address entered here. One typo and the renewal reminder never arrives.
Trying to leave the phone empty. Phone is required; payment providers generally ask for it.
Typing a company name into "Full name" without ticking the box. The invoice is then issued without tax details.
Writing a tax number with spaces or dots. The number is stripped before validation, but if it is still refused, check the digit count.
Buying before correcting the country. A wrong country means a wrong tax rate and missing payment methods.
If a field refuses to save, the red line under the form tells you which one; if that does not resolve it, contact our Support team.
